To all whom t may concern:

Be it known that I, MILES E. LOEHR, a citizen of the United States, residing at lVarsaw, in the county of Kosciusko and State of Indiana, have invented certain new and useful Improvements in. Pumps and Cleaners for Acetylene-Gas Generators; and I do `hereby declare the following to be a full, clear, and exact description of the invention, such as will .enable others skilled in the art to which it appertains to make and use the same. Y.

This invention comprehends certain new and useful improvements in pumps and cleaners for acetylene gas generators and has for its primary object to provide a device of this character which may be readily incorporated in acetylene gas generators of the form now in use to remove the residue from a generator casing with one operation.

The invention has for another object to provide a pump and cleaner of this character including a telescoping discharge pipe positioned between the generator and the generator 'casing so that the pump or discharge pipe may be moved out of position between the generator and casing when not in use.

The invention has for another object to provide a pump and cleaner for acetylene gas generators which will be of such form that the operative parts of the cleaner may be positioned beneath the'bottom ofthe generator with the latter supporting upon the arms employed for spacing the cleaner from the inner wall of the generator casing.

The invention has for a further object to provide a pump and cleaner for acetylene gas generators which will be of suchv construction and operation that the pump and cleaner may both be operated with onehand to gather the residue from the bottom of the casing of the generator and convey the same to the discharge pipe to be sucked up through the same by the piston of the pump.

The invention has for a still further object to generally improve and sim lify the construction and yoperation of a evice of'this character and increase the efliciency thereof without materially increasing the cost of the Same.

be hereinafter more fully described and claimed.

For a complete understanding of my inyention, reference is to be had to the followlng description and accompanying drawings, in which- Figure 1 is a vertical section through a generator and'casing with my pump and .cleaner positioned therein,portions of my invention being shown'in section, Fig. 2 is an enlarged elevation, partly in section of the cleaner, and lower portions of the generator casing, Fig. 3 `is a detail perspective view of the revolving cleaning spout removed, and Fig. 4 is a detail view of the reciprocating pump and cleaner rod with the parts carried thereby removed and the pump handle turned to swingthe reciprocating pump rod and plunger to one side. v

Referring more particularly to the drawings, in whichA similar reference characters designate correspondingparts throughout the several views, 1 designates the casing within which the tank 2 of an acetylene gas generator is positioned. The' bottom 3 of the tank 2 rests upon the outwardly directed horizontal ends 4 of the inclined spacing arm 5 extending from the flange 6 formed on the lower downwardly turned end 7 of the discharge pipe 8 of the pump, it being understood that the ends 4 of theV arm 5 have their free extremities 9 directed downwardly and engaged against the inner face of the casing 1 and are preferably secured to the same in some well known or preferred manner. The flange 6 is positioned in the longitudinal center of the casing 1 a spaced distance above the bottom thereof, while the main portion of the discharge pipe S extends vertically between the tank 2 and casing 1. The lower portion of said pipe S is directed inwardly in a horizontal plane as shown at l0 before being bent or curved downwardly. An upper discharge pipe section 11 is telescopically mounted upon the discharge pipe 8 and hasan enlarged or flared upper end 12 with a spout 13 projecting from the side thereof, the upper end of the discharge pipe section 11 being preferably closed, as shown at 14. The upper discharge pipe section 11 also has a downwardly directed hook 15 formed on its outer face for engagement over the upper edge of the casing l to support said pipe section 11 in extended position with the discharge spout 13 directed outwardly from said casing 1.

Reciprocally mounted through the en d14 of the extension pump discharge pipe 11 is the reciprocating pump rod 16 which has a valved piston 17 mounted on its 'lower end within the discharge pipe 8 above the normally closed flap valve 18 in said dischargei i verse strip and has depending from its vso outer endsthe reciprocating rod 2O which has the downwardly inclined link 21 eX- tendedtherefrom with the longitudinal slot 22 formed therein, withinl which engages a pin 23 mounted upon the upper end of the rock arm'24 to'rock thesame upon a central pivot pin 25. The pivot Vpin 25 is eX- tended to a suitable support,- (not shown) extending inwardly from the sides of the casing 1 a spaced distance from the bottom thereof. As the handle'19 is moved upwardly and downwardly to reciprocate the pump piston rod 16, the rod 20will also be reciprocated, thereby moving upwardly and downwardly. The inclined link 21 which is rigid with the rod 20, allows the pin 23 to travel from one end tojthe other of the slot 22 and thereby rocks the rock arm 24 upon its pivot 25 to swing horizontally a pawl operating rod 26 which has its outer end pivoted in the bifurcated lower end of the rock arm 24 while the inner end of the rod 26 is pivoted in the spaced arms of the stationary bracket -27 secured upon flange 6 Vof the downwardly directed end 7 of the discharge pipe 8, thereby moving the pawl 28 into engagement with the ratchet wheel 29 secured around the upper end of the rotating sleeve 30 to rotate said sleeve 30 upon the lower extremity of the discharge pipe 8. The rotary sleeve 30 has its lower end closed while its upper end is open and a pivot strap 31 depends from the bottom of said sleeve 30 and is engaged in a suit,- able bearing slot 32 mountedon the bottom of the casing. 1. v i

A residue revolving gathering'inger 33 which is of substantially triangular form in plan has its inner end connected with the outer face ofthe rotary sleeve 30 while one side of the gathering finger, preferably the forward side is open and the bottom of said linger has its central portion-cut away, as shown at 34, whereby the residue in the bottom of the casing 1 'may be readily gath- V ered as the sleeve 30 and finger 33are rothe center of the linger 33 to enter the outer end of the projecting Ypipe 35 and be conveyed by the same to the interior of the sleeve 30, at which place it is drawn upwardly upon operation of the handle 19, as stated. lThe conducting pipe 35 is within Vthe linger 33 and extends from the center thereof tothe inner end and has communi# cation with the interior of the sleeve 30. The outer curvedend 36 of the finger 33 is positioned adjacent the lside or vertical wall of the casing 1, thereby causing the nger 33 to gather all Iof the residue between the rotating sleevey 30 and the side walls-of the casing 1 as the vsleeve 30 and' finger 33 are rotated, thev bottomofy thesleeve 3() resting upon the bottom of thecasing'l.'VV From the foregoing it will be're'adily seen that the residue maybe gathered from the bottom-of theY casing land drawn upwardly through the discharge pipes A8v andy 11 Aand, forced out of the discharge V spout v13 with one operation'which may be accomplished with one hand ofthe operator. It will also j be seen thatV the Vconstruction and operation of the parts of this 'device are extremely simple and the apparatus 'may be readily incorporated inv generators of the typenow the spirit of the invention or sacrificing any Y i of the advantages thereof.

What is claimed is I o 1. A device of the class describedincluding the combination with' a gasgenerator casing, brackets secured in said casingk adjacent the bottom thereof, andra tank seated in said gas generator casingupon the upperA portions of the brackets, yof a discharge pipe positioned vertically between'the casing and tank, the upper end of saidV pipe extending outwardly beyondthe upper edges Tof the casing, the lower endfof'said pipedirected inwardly and downwardly andpositioned directly under the bottom ofthe tank, ya
